Well it certainly has an impact on my mood, I become very giddy when my blood sugar is dropping, but if it's higher then I'm very flat, anything into the teens and beyond and I become very angry, and on one occasion aggressive (verbally, I'm a lover not a fighter!). It was my moods that people noticed before diagnosis. I'm generally very very level, so swinging between giddiness and mild snarkiness was a red flag.
have you been diagnosed with diabetes, or are you wondering if you're diabetic?
